The Queen Bey has spoken. On Tuesday, March 26 -- the first day of the Supreme Court hearings on California's Prop 8, a ban on same-sex marriage -- Beyonce made her position on the issue crystal-clear when she shared a short but stirring handwritten note in support of marriage equality. The message, which the superstar posted to Instagram and Facebook, was written on red paper in a nod to the Human Rights Campaign's use of the rosy hue to symbolize love for all.

"If you like it you should be able to put a ring on it," Jay-Z's wife wrote, riffing on the lyrics to her smash hit "Single Ladies (Put a Ring on It)." Beneath that, she added the hashtag "WeWillUniteForMarriageEquality."

Within 15 hours, the note had more than 211,000 "likes" on Instagram and over 30,600 shares on Facebook. "It's about time," the "Love on Top" singer, 31, said in another picture, which featured the hashtag "MarriageIsLove." "Show your support!"

"Today, the Supreme Court is hearing one of the most important cases in history," House of Lies actress Kristen Bell wrote. "Don't sleep on it. Equality matters." (The pregnant star and fiance Dax Shepard have said they won't wed until same-sex marriage is federalized.)

Beyonce's husband voiced a similar sentiment last May. "I've always thought it was something that was still holding the country back," Jay-Z, 43, told CNN of the ban on same-sex marriage. "What people do in their own homes is their business and you can choose to love whoever you love. That's their business. It's no different than discriminating against blacks. It's discrimination, plain and simple."
